Ultra-high-performance concrete [UHPC]
Ultra-high performance concrete (UHPC) is a modern composite material with extremely good mechanical characteristics. UHPC is more homogeneous than NSC due to optimized packing density and limited use of coarse aggregates. The size and strength difference between the matrix and the fine aggregates are so small that under external …
